To (ill whom it may concern..- I.

Be it known that we, LABAN.B. LAKE and EDMUND SswyER, both citizens of the United .States', residing at Toledo, in the county .of

r 5 'Lucas and State of Ohio, have invented new and useful Improvements in Adjustable Holde'rs forEBooks and Sheet-Music on Organs and Pianos','of whichthe following is a specificatlon.

- Our invention relates to improvements in devices for holding sheet-music and music-v books in 'a desired position on the-music-rack of a piano or organ, or on portable racks for music when playing with any other'instrument; and the objects of "our improvements are to provide a cheap, simple, and durable I device forthe purpose that may be built on the music-racks when the instruments are constructed, or a device made so as to be easily attached to or detached from the music-rack i of any instrument, and at the same time ad justable, so as to adapt its use to any sized book desired; These objects we attain in the manner hereinafter specified, and shown in the 25 drawings illustrating the device hereto annexed, in which'-- a Figure 1 is a face view of'a rack with the device built upon it. Fig. 2 is an edge'view from the top of the same, showing the device holding a book in the proper position.

' Figs. 4 and; 5 are edge-andendviews of the holder, as constructed separate and made attachable to and detaehablefromany music-rack of a piano or' x5 organ. Figs. 6 and 9' are enlarged details of parts that slide and turn. Figs. 7 and-8 are views of a modified form of the device, showing a dovetailedblock sliding in a groove.

- A represents an ordinary piano or ,organ music-board, made either of slats or in fretslat, 0, having the edges out under in the form of a tenon of adovetail'joint. E is a sliding clamp-plate on the raised slat 0,, to which is pivoted aspring-cla'mp, R, that may be swung around in any direction desired on the pivot e.

; B is the ordinary base-ledge,upon which the.

book Drests, v r Figs'l, 2,'and 3 show the difieren views of the device as "built on the rack.

Fig.

tachable or detachable to the music-board of any organ or piano in which apiece having two sections, 0 and O", is worked out and fin- 5 ished'like a piece of molding, the edges of which have a double bevel to receive the adjustable slidingclamps E andL. The sliding clamp-plate E has pivoted to it ate thespringclamp H, which may be turned, as desired, to 6p replace -or adjust the book. The sliding clamp-plate IJ has a shorter spring clamp or arm, K,-extending out from 'it, which is designed to pass through the openings in theordinary music-racks on organs and pianos, and 6E' J clamp over some of the members of the same i.

and to meet all demands, and adapted tobe attached at any place. The clamp L may he slid off at the end and reversed.

In cases where the folding of a piano or organ requires a more compact device, we design to use a modified form, (shown in Figs. 7 and 8,) in which, instead of the sliding clampplate E on the raised slat C,' thc bevel-edged block I slides in a dovetailed groove below the 5 face of the slat O, accomplishing substantially the same end and purpose. The slat on which the clamp slides will be provided at each end,

as illustrated in Fig. 1, with'aslot-pin, h, to

check the movement of the slide and protect it from passing entirely from oh the slat. The parts of this device we design to make of any suitable metal and finish in accordance with the class of work to which it is to be attached, cushibning with felt or baize those 8;

parts which by use tend to mar the'finish. of the instrument, The l'en'gthand other dimensions of the device and its parts we design to make suitable for any sized book desired. I We are awarethat it is old to providespringo fingers that can. be turned and adjusted to sup; port, books of different sizes. We are-also. aware that a music-holderhas been constructed of a plain rectangular'bar without grooves or incisions, withtubes entirely surrounding the 5 same and sliding thereon, said tubes being provided with springs for clamping the leaves.

of a book, and the bar having .ofi'sets at each end. Such, therefore, we do not claim.-

Having thus described our invention so that on,

anyone skilled in the arts can make and use VIE), providedrrwith spring-clamp K, the said 15 the same, what we claim as new, and desire to 'elampplates, being dovetailedto conform to seeure by Letters Patent, '1's ':1. .;In e holder for sh 5 e combination with a sides nndpro'vided with formed to fit'the beveled a spring-finger, H, of ela 'fdineetly-to the f lyasdeseribed.
